以Bean结尾，表示它是一个Bean，不同于普通Bean的是：它是实现了FactoryBean
例如自己实现一个FactoryBean，功能：用来代理一个对象，对该对象的所有方法做一个拦截，在调用前后都输出一行LOG，模仿ProxyFactoryBean的功能。
shiro中就利用facoryBean的getObject()返回Ini.Section对象注入动态权限
/**
* my factory bean
* 代理一个类，拦截该类的所有方法，在方法的调用前后进行日志的输出
* @author daniel.zhao
*
*/
public class MyFactoryBean implements FactoryBean
private static final Logger logger = LoggerFactory.getLogger(MyFactoryBean.class);
private String interfaceName;
private Object target;
private Object proxyObj;
@Override
public void destroy() throws Exception {
logger.debug("destroy......");
}
@Override
public void afterPropertiesSet() throws Exception {
proxyObj = Proxy.newProxyInstance(
this.getClass().getClassLoader(),
new Class[] { Class.forName(interfaceName) },
new InvocationHandler() {
@Override
public Object invoke(Object proxy, Method method, Object[] args) throws Throwable {
logger.debug("invoke method......" + method.getName());
logger.debug("invoke method before......" + System.currentTimeMillis());
Object result = method.invoke(target, args);
logger.debug("invoke method after......" + System.currentTimeMillis());
return result;
}
});
logger.debug("afterPropertiesSet......");
}
@Override
public Object getObject() throws Exception {
logger.debug("getObject......");
return proxyObj;
}
@Override
public Class getObjectType() {
return proxyObj == null ? Object.class : proxyObj.getClass();
}
@Override
public boolean isSingleton() {
return true;
}
public String getInterfaceName() {
return interfaceName;
}
public void setInterfaceName(String interfaceName) {
this.interfaceName = interfaceName;
}
public Object getTarget() {
return target;
}
public void setTarget(Object target) {
this.target = target;
}
public Object getProxyObj() {
return proxyObj;
}
public void setProxyObj(Object proxyObj) {
this.proxyObj = proxyObj;
}
}
XML-Bean配置如下
12 3 4
@RunWith(JUnit4ClassRunner.class)
@ContextConfiguration(classes = { MyFactoryBeanConfig.class })
public class MyFactoryBeanTest {
@Autowired
private ApplicationContext context;
/**
* 测试验证FactoryBean原理，代理一个servcie在调用其方法的前后，打印日志亦可作其他处理
* 从ApplicationContext中获取自定义的FactoryBean
* context.getBean(String beanName) ---> 最终获取到的Object是FactoryBean.getObejct(),
* 使用Proxy.newInstance生成service的代理类
*/
@Test
public void testFactoryBean() {
HelloWorldService helloWorldService = (HelloWorldService) context.getBean("fbHelloWorldService");
helloWorldService.getBeanName();
helloWorldService.sayHello();
}
}
